METAL BARREL.

Application filed March 8, 1917.

To all whom it may concern.'

lie it known that I, Join: JAsziiUL, a subject ot the Emperor of hussiaqand residing at Maspeth. Long Island, in the county ot Queens and Stateof New York. have invented a certain new and useful Improve'- ment inMetal Barrels, of which the following a specification. j

My invention relates to metal barrels and particularly to improved meansfor securing the barrel end to the barrel body. the object ot mvinvention being to provide a tight, strong joint betweenthe parts whichwill withstand injury from rough treatment during shipment.

Referring to the accompanying drawings;

Figure 1 is a broken side elevation, partially in section.` of a barrelin which my invention is embodied;

Fig. 2 is a partial vertical section through the barrel end and lockingring detached;

Fig. 3 is a similar view of the locking ring and barrel end assembledand in position to enter the barrel body;

Fig. 4 isa Isimilar view showing the barrel end crimped upon the lockingring;

Fig. 5 is a similar view showing the inv ner or holding flange of thelocking ring crimped down upon the joint between the barrel end andbody; and

Fig. G shows the outer or protecting flange Itocover and secure thejoint.

The present invention particularly relates to metal barrels' such as arecommonly used :tor shipping oil, gasolene and other substances which arelikely to vaporizeand create pressure Within the barrel. In barrels oitthis type the danger of leakage is very great and the joint between thebarrel end and the wall of the barrel must be very secure in order tokeep the barrel tight. My invention relates to means for effecting sucha joint and comprises a novel and improved locking ring which not onlyinsures atight joint when the barrel is made, but is suiiiciently strongand rigid to withstand the shocks incident to rough handling duringtransportation. As here shown this locking ring comprises an annulus 10of any suitable metal, preferably malleable steel, shouldered at 11 andhaving outwardly extending flanges 12 and'13 integral with the outer endot the ring lying beyond the shoulder 1l. The diameter of the inner endof the ring is such that it fits snugly within the upstanding flange itOf the cupped, barrel Specication of Letters Patent.

end closure 15, and this flange 14 is of such depth that it extendsbeyond the shoulder 11 so that it may be rolled or crimped into thechannel 16 formed between the shoulder 11 and the flange 12, asindicated in Fig. 3, thus locking the ring 10 to the barrel end. Thering and barrel end thus assembled may be set into the open end of thebarrel 17, the edge 18 of which is positioned against the flange 12, andthen similarly crimped or rolled into the channel 16 above the flange14; of the end closure 15, as indicated in Fig. 4,. This operationunites the ring 10 and closure 15 joint is not strong enough towithstand internal pressure, or the shocks incident to shipment. Inorder to render it so, I roll down the short flange 12 at the outer endof the ring into `the channel 1G and thus clamp the parts together in ajoint which is absolutely leak-proof even under a relatively highinternal pressure, say up to thirty pounds per square inch. To reinforcethis joint and protect the flange 12 against opening or injury incidentto rough handling i roll down thereover the outer flange 18, the vlatterbeing et' sufficient length to completely overlap the joint and extendinward to a point beyond the shoulder ll'on the annulus 10.

By making the flange 12 relatively 'light it is possible to roll it intovthe'channel 16 above the oilset ends of the closure flange 11i andbarrel Wallin such a manner as to render the joint much tighter than isnow commonly secured. while the protecting outer flange 13 affords allthe necessary strength and rigidity to withstand the shocks and strainsincident to shipment. Moreover, both flanges 12 and 13 may be lighterthan is now customary in locking rings for barrels of this type and thisfact puts much less strain upon the machines which are employed forrolling or crimping the flanges. This not only expedites the operation,but also prevents the breakage of the crimping machine which is now anall too frequent occurrance,When it is attempted to push the machinesfor rapid Work.

Various modifications of details of design, structure and proportionwill readily occur to those skilled in the art which do not depart fromwhat I claim as my in vention.

I claim 1 l. 1n a metal barrel, an end closure lock,`$

to the barrel body, but the ing ring having an external shoulder forforming joint with the barrel body and end closure, and outwardlyextending spaced flanges at the outer end of the ring adapted to becrimped down upon the joint formed at the ring shoulder, substantiallyas described.

2. In a metal barrel, an end closure locking ring having an externalshoulder for forming joint with the barrel body and end closure, andoutwardly extending spaced ilanges at the outer end of the ring adaptedto be crimped down upon the joint formed at the ring shoulder, the endflange being of greater width and extending inward beyond the shoulderin the finished joint, substantially as described.

3. In a metal barrel, a cupped ond closure having a marginal flangeadapted to fit within the barrel body, a shouldered locking ring fittingwithin the marginal flange o f the end closure and having at its outerend outwardly extending spaced flanges, in the finished barrel the endclosure flange and barrel body wall being offset over said shoulder onthe locking ring and Copies of this patent may be obtained for ve centseach, by addressing the the flanges on the latter being rolled down uponthe joint so formed, to secure and protect the latter.

4. In a metal barrel, a cupped end closure having a marginal flangeadapted to it with in the barrel body, a shouldered locking ring fittingwithin the marginal flange of the end closure and having at its outerend outf Wardly extending spaced fia-nges, in the finished barrel theend closure flange and barrel body Wall being offset over said shoulderon the locking ring and the flanges on the latter being rolled down uponthe joint so formed, to secure and protect the latter, the outer of saidflanges extending inward boyond the joint and serving to protect theinner flange against injury incident to rough handling duringtransportation.

In testimony. whereof I have signed my name to this specification, inthe presence of two subscribing witnesses.
